EPC网络的跨层架构研究

Design and Implementation of Cross Layer Architecture for EPC Network

由阅读器(Reader)、感应器(Transponder)与中介系统(Middleware System)三者串联而成的无线射频对象识别系统,形成未来生产线自动化、物料管理与物流业的新兴架构将大量使用射频识别RFID,本文论述了RFID/EPC network跨层设计(Cross Layer Design),将RFIDcode跨层技术直接运用于EPC网络,并将EPCcode跨层应用于ONS Framework.通过此跨层设计,用户可通过智能型手机与RFID阅读器读取RFID code,并将此RFIDcode直接由EPC网络查询并取得商品的信息;而EPCcode跨层设计可直接使用EPCcode,对ONS Framework查询并追踪商品的动向.本论文所提出的Cross Layer Dsign架构能够减少EPC网络负荷与使用者查询需要的等待时间.

The RFID framework,comprising a Reader,a Transponder and Middleware system,is increasingly popular in production line automation,material management and the logistics industry.This paper proposes a cross-layer design based on RFID/EPC network.The proposed design incorporates a RFID smart phone in the Physical layer;transfers the RFID code into the EPC Network at the Media Access Control Layer;accumulates the EPC Domain Information at the Application Layer.The cross-layer approach allows an user to purchase goods on the smart phone with a RFID reader,and records the commodity information by ONS Framework.According to the experimental results,the proposed cross layer architecture reduces the traffic load and waiting time of EPC network.
